Serial No. 629,207

1 Claim. (01. ss-m) This invention appertains to new and useful improvements in the art of refrigeration, and more particularly to a novel refrigerator of the electrical type, which has as its principal object.

5 the'provision of'means whereby the same can be handledin a portable manner.

Another important object of a... invention is to provide a portable refrigerator, wherein means is involved whereby the refrigerator can be posio tively secured to the'rimningboard of an automobile.

- Other important objects and advantages of the invention will.become apparent 'to the reader of the following specification. a is In the drawings:----

Figure 1 represents a front elevational view of the novel device.

Fig. 6 represents an elevational -view of the handle for the food compartment door. Fig. '7 represents a diagrammatic view of the refrigerator system.

Fig. 3 represents a top plan view of the battery holder.

Fig. 9 represents a ditic view of the electrical circuit.

Fig. 10 represents an end elevational view of the refrigerator shown secured .to the running board of an automobile. v

Fig. 11 represents a top plan view of the holding attachment for running boards.

Fig. 12 represents a sectional view taken substantially on line ill-12 of Fig. 11.

als designate like parts, it can be seen that the refrigerator consists of a casing, having a top wall 5, end walls 6-7, a bottom 8, a fro'nt wall 9 and a rear wail 1c. The interior of this casing is divided by the partition 11 into the chamber 12 and the food compartment 13.

Numeral 14 generally refers to the freezing ele-' ment of the refrigerator, located within the food compartment 13. In this compartment 13 is located the thermostat 15 as well as a plurality of vertically spaced shelves 16.

Numeral 17 represents suitable means for sup-. porting or suspending the 1 elements 14 switch 49.

within the chamber 13. Referring to Fig. 4, taken with Fig. 8, it can beseen that within the bottom of the mechanism chamber 12 is placed the ushaped frame 18 for receiving the storage battery 19, one end of the frame 18 having the bar 20 hingedly secured thereto as at 21. This bar 20 is swin'gable and secured at its free end to the remaining end of the frame 18 as at 22, to retain a battery 19 in the manner shown in Fig. 4, below the platform 23 in the chamber 12. Upon the platform 23 is mounted the usual compressor 24 which is driven by the electric motor 25 by way of the'pulleys 26-27, and belt 28. The fluid tank 29 is also located within this chamber 12 as is the condenser 30.

Within the chamber 13 at a suitable point islecated the expansion valve 13. The front wall 9- of the cabinet or casing has a door 32 for the mechanism compartment 12 and a door 33 for the food compartment 13. The doors 3'2 and 33 are provided with sockets 34 the interior wall of which is provided with a groove for receiving the spring pressed pawls 35 .on the reduced extension 36 of a handle orknob 37, whereby the usual latch of the door can be 0 manipulated. v

For securing the refrigerator in place upon a running board 38 in the manner shown in Fig.

' 10, a pair of L-shaped members 39 of angle iron are hinged togetheras at 40 to provide 9. rectangular-shaped frame, the sections of which are provided with inwardly-extending teats 41.

The free ends of the sections of-this frame are connectible together as at 42. Asia clearly shown I in Fig. 10, an arm extends downwardly and under the frame and this is-denot'ed by numeral 43. A clamp screw 44 is feedable upwardly through the arm 43 and against the running board 38 to secure the frame firmly to the running board ;38 and obviouslywith the fastening 42 and the refrigerator mounted within the frame, the Referring to the drawings wherein like numerf aforementioned teats 41 are engaging into the recesses .45-on the" lower portion of the casing (see Fig. 2). v

Fig. 9 shows the electricaldiagram whereby 10o which hasits secondary in circuit with the motor 25 of the refrigerator. In this circuit, which will be. denoted by numeral 48, is located a manual When the refrigerator is to be used with com I mercial current supply, the switch 49 is closed.

'It will be observed that the motor 25 is also A refrigerator of the character described comprising a portable casing, said casing having a partition therein, said partition dividing the casing into a food compartment, and a mechanism compartment, a closure for each of the said compartments, a. mechanism supporting platform in said mechanism compartment dividing said compartment into upper and lower chambers, and a storagebattery in said lower chamber, the remainder of the operating mechanism being located in said upper chamber and supported by said platform.
